چکیده
Reaction of cis-diazidobis(ethylenediamine)cobalt(III)nitrate with ammonium thiocyanate in a 1 : 2 molar ratio in aqueous medium gave the title cobalt(III) compound, cis-[Co(en)2(N3)2]SCN, as reddish brown crystals in almost quantitative yield. The complex salt was characterized by elemental analysis, IR, electronic, H and C NMR spectroscopic studies. An X-ray structure determination revealed an ionic structure with the monoclinic space group P21/c, having cell dimensions a1⁄4 12.1950(6), b1⁄4 9.0317(5), c1⁄4 12.6017(7) Å; 1⁄4 113.419(1) , V1⁄4 1273.63(12) Å and Z1⁄4 4. The structure was refined by a full-matrix least-square procedures to R11⁄4 0.0297 and wR21⁄4 0.0697.

Why is there an "inert" metal center in the active site of nitrile hydratase? Reactivity and ligand dissociation from a five-coordinate Co(III) nitrile hydratase model.
To determine how a substitutionally inert metal can play a catalytic role in the metalloenzyme nitrile hydratase (NHase), a reactive five-coordinate Co(III) thiolate complex ([Co(III)(S(2)(Me2)N(3)(Pr,Pr))](PF(6)) (1)) that resembles the active site of cobalt containing nitrile hydratase (Co NHase) was prepared. This was screened for reactivity, by using low-temperature electronic absorption sp...

Thiocyanate hydrolase (TCH) is a pink bacterial metalloenzyme found in Thiobacillus thioparus THI 115 that catalyzes the conversion of thiocyanate to carbonyl sulfide and ammonia.1,2 Although TCH has not been well characterized spectroscopically, an analysis of the genes encoding for the enzyme has shown a high active-site sequence homology to the metalloenzyme nitrile hydratase (NHase), includ...
